A comparison Study between Virtualized and non-virtualized Environments

Abstract

Hardware Virtualization has become an important technology nowadays because it provides excellent technical features for the present as well as the futurethrough the provision of significant advantages for instance saving the Hardware expenses. The research aims to compare Virtualized Environments to non-virtualized environments, and the Xen Technology which is chosen in this research is one of the leading technologies in the hardware virtualization field. The comparison based on two pivots, the first measures the Memory performance (RAM) and the second measures the processor performance,to obtain results that reflect the real difference between the two environmentsperformancesthatused the same hardware specifications and the same size and structure of data, thisdata is part of ERP system that belong to one of Sudanese companies. The results that we have acquired reflect the substantial convergence and very small differences in performance between the Virtualized Environments and Non-visualized Environments, and beyond that the research found that in case of large data the virtualized Environments give better performanceresults than non-virtual environments that is due to tuning and better management provided by virtualization tools.
